Introduction

Masaya Asai, an accomplished inventor based in Kyoto, Japan, has made significant contributions to the field of film processing technology. With a remarkable portfolio of 19 patents, Asai has demonstrated his expertise and creativity in developing innovative solutions for substrate processing.

Latest Patents

Asai's recent inventions include a sophisticated film processing method that involves the utilization of a nozzle stored in a nozzle storage hole of a waiting pod. In this innovative process, a cleaning liquid is discharged from multiple discharge ports onto the outer peripheral surface of the nozzle, effectively dissolving and removing any coating liquid and solidified matter adhered to it. The procedure continues with a metal removal liquid that is similarly applied, ensuring that any remaining metallic components are eliminated. Finally, pure water is used to cleanse away any residual metal removal liquid from the nozzle's surface.

Additionally, Asai has developed a substrate processing apparatus, including a film formation unit and methods for processing substrates and film formation. This involves supplying a metal-containing coating liquid to the surface of a substrate, which subsequently transports the substrate to a metal removal unit, where a specially formulated removal liquid is applied to dissolve the metal-containing coating film, while preserving the film in designated areas of the substrate.
